ok my car was idling rough and i just replace plugs, wires, and coil pack. (also fuel filter) all my coneections are good. my car started idling bad again after a quick burst of fun fun acceleration. read code 342, fuel pump secondary. checked fuel pressure. 41 psi. good. i have no clue why my car is running bad. just a second ago it wouldnt start, but its the 30 amp fuse to the ignition coil. hmph, get a new one then back where i started.i gaped the plugs at about .053 like on the sticker, bt ive heard .045 is better. but this wouldnt effect the car that much? advice please.
